Type generation without $id parameter

I'm trying for the first time appwrite on 2 projects and after I've tested appwrite types generation with the cli I'm a little bit confused why it doesn't include or handle the $id field which is fundamental to handle relationships.

I'm not finding anything about it in the documentation and I understand that it is reported that the relationships are in an experimental phase but rather it makes me think that I'm doing something wrong or is it intentional?

What is the best way to relate collections of documents in this case?

Thank you very much 🙂

$id and similar attributes are apart of the models provided by appwrite. Your type should extend appwrites base type. Does the type generator not do this?

Similar to this

export type Books = Models.Document & {
  name: string;
  author: string;
  releaseYear: string | null;
  category: Category | null;
  genre: string[] | null;
  isCheckedOut: boolean;
}

We are extending the Models.Document type, which includes $id, $createdAt, etc.

I only saw right now that when generating types with -l ts option it does generate the extended classes, but this doesn't happen for dart and PHP. 🤔

seems like only ts pulls with the base types. idk if that's intended or not. Seems weird to me.
